Web Based Business Application At LHIND

In a large-scale program for a well-known automotive customer, our team built an application to clean up, enrich, and visualize a catalog of work operations/positions. Beyond exploration and reporting, the application includes calculation logic that processes user-selected items and returns an aggregated time estimate for the chosen scope—turning complex operational data into actionable results.

The solution is part of a larger distributed system and is designed for high data throughput: it ingests substantial data volumes from upstream sources, applies domain rules and transformations, and exposes curated data to other services. Architecturally, we follow a microservice approach and apply Domain-Driven Design (DDD) principles to keep the domain model clear, maintainable, and aligned with business terminology.

I contribute as a full-stack developer end to end—from implementation to delivery — and I’m also involved in Docker-based deployments and CI / CD pipelines on Amazon Web Services (AWS). While I work across the stack (Java & Spring on the backend, Angular & TypeScript on the frontend, and Python where it fits best), my main focus is the frontend. In particular, I was able to drive noticeable UI / UX and maintainability improvements compared to a predecessor solution, leveraging Angular and the GroupUI component library to build a consistent, scalable interface.

A small personal note: during my studies I was very “backend-first” and considered frontend more of a necessary evil. When our frontend lead left the project, I volunteered to take over and preserve the lead's knowledge—and to my surprise, that quickly turned into genuine enthusiasm for frontend engineering. It was a good reminder that the best way to grow is often to challenge your own assumptions.
